Red Oak Tax Refund Calculator iPhone app

The aim of my project is to develop a prototype

for a

comercial iPhone app for the Red Oak Tax Refunds Company

of

their Tax Refund Calculator.The calculator will be formed to give the estimated tax refund of an user.Slide3

This calculator is aimed at PAYE income tax payers and cover

s

most scenarios.

Tax Refund Calculator as an iPhone app will play

a

significant role to encourage the customers to Red Oak to get a full Tax Refund Assessment.Slide4

The user can

either proceed to next step by touching the

"Next Step" button or by using the segmented control.Slide6

information

about principle residence

.

"Reset" button is also provided, if the user wishes to reload the calculator.Slide7

This screen shot

is

the

last step of the calculator called "Expenses" that allows

the

the "Submit" button.

How this is different from a regular application?

Mobile applications are not just ported small desktop applications.

Mobile phones have a small screen and are task-focused.

Mobile phones have limited CPU and Memory.

Only one application can run at a time.Slide11

Objective-C

Object-oriented language.

Extension of the standard ANSI C language.

There is no garbage collection mechanism.

The programmer has to keep track of when to free allocated memory to not cause memory leaks.Slide12

Objective-CSlide13

Xcode

These are the tools that I’m using for

iPhone

app development.

From left to right; Library,

xib

View,

Xcode

IDE and Inspector.Slide14

iPhone

Simulator

The simulator which let me test most of the functionality locally on the iMac.Slide15

Technology

Option

The environment

my

iPhone

app is written in is Xcode.

Objective-C

and

Xcode

are

the only

ways to

develop an iPhone app. Intel-based Mac is another compulsory technology. Slide16

Potential Issues & Challenges

Memory management is one of the challenges since iPhone has limited resources

.

Currently testing relies on iPhone Simulator, however, iMac has lots of resources.

Testing on the actual device (iPhone or i

Pod Touch) will be more important due to reliability issue.

You have to

enroll

in the

iPhone

Developer Program and pay $99 to test in a real device and release onto the App Store.

Getting updates and

the

contact f

orm functionalities working.Slide17

Remaining Works

I am working on connections between the tab bar items and the views. The rest of the connections were made.

I will start coding calculations soon.

I have to establish communication channel between the customer and the company via

the

contact form.

Update d

ownload

functionality for the calculator has to be done.Slide18
